1. A transmission welding method for welding a first workpiece part, which is formed at least partially from thermoplastic material, to at least one second workpiece part at a weld point, the method comprising:
providing an infrared lamp within at least one bracing element in a form of a tube;
a) bracing the first workpiece part and the second workpiece part by at least one bracing element and pressing the at least one bracing element onto the first workpiece part;
b) directing, using an infrared lamp that is internal to the tube of the at least one bracing element, polychromatic, incoherent infrared light radiation through the at least one bracing element to the first workpiece part and through the first workpiece part to the weld point;
c) setting a temperature of the at least one bracing element before, during, and/or after step b) to influence a temperature of at least one region of the first workpiece part; and
moving the tube, with the infrared lamp contained therein, over the first workpiece part along a welding region;
wherein the tube of the at least one bracing element is at least partially transparent to the infrared light radiation;
wherein at least one region of the first workpiece part or all of the first workpiece part is formed from a thermoplastic fiber composite material; and
wherein the infrared light radiation is directed through the thermoplastic fiber composite material of the first workpiece part to the weld point.
